如何在 iOS 中监听通知解除事件? [英] How to listen for notification dismissed event in iOS?

问题描述

我正在监听为我的本地通知按下的操作，但有没有办法确定用户何时取消通知?

I am listneing to actions pressed for my local notifications, but is there a way to determine when the user dismisses a notification?

以下是我在 AppDelegate 中监听我的操作的方式，但关闭不会触发:

Here is how I'm listening to my actions in my AppDelegate, but the dismiss doesn't fire this:

func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler: () -> Void) {
        var actionName: String? = nil

        if let identifier = identifier {
            switch identifier {
                case "snoozeAction":
                    actionName = "snoozeActionTapped"
                    break
                default: break
            }

            if let name = actionName {
                NSNotificationCenter.defaultCenter().postNotificationName(name, object: nil)
            }
        }

        completionHandler()
    }

推荐答案

关闭通知不会唤醒您的应用程序，因此无法捕获此信息.

Dismissing a notification does not wake your application up so there is no way to capture this.
